| Abstract: | Based on years＇ experiences of oil and gas linepipe production, the standards for such products are discussed. As a result, proposals for supplements to certain contents of the standards are put forward, covering such aspects as guided-bend test, lot sampling for physical-chemical property tests, inclusions, yield to tensile ratio, minimal chemical composition, metal Vickers hardness test, radial offset, misalignment and hydrostatic test pressure etc. |
